Identifying consumers via facial recognition to provide services

ABSTRACT

A user signs into an application via a user computing device at a merchant system location. The user computing device receives an identifier from a beacon device at the location to transmit to an account management system. The account management system transmits facial templates to the merchant camera device for users who are signed in to the application in range of the merchant beacon device. The user approaches a point of sale device to purchase a restricted product or service. The merchant camera device compares a captured facial image against the received facial templates to identify the user. A merchant POS device operator, after determining that the user is eligible for the restricted product or service based on account information of the user, selects a payment account of the user. The merchant POS device transmits transaction details to the account management system, which processes the transaction with an issuer system.

CROSS-REFERENCE TO RELATED APPLICATION

This patent application claims priority to U.S. Patent Application No. 62/155,466, filed Apr. 30, 2015, and entitled “Identifying Consumers via Facial Recognition to Provide Services.” The entire content of the above-identified application are hereby fully incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to improving user convenience in transactions and other merchant services by identifying user accounts based on facial recognition of users by an account management system.

BACKGROUND

When consumers make purchases of goods or services at a merchant location, many methods of conducting a transaction are available. Consumers may use many different cards or accounts for purchases, such as gift cards, debit cards, credit cards, stored value cards, and other cards or accounts. The user account identifiers and other data represented by the cards may be communicated to the merchant system via magnetic stripes, near field communication technologies involving user computing devices, and other suitable mechanisms. Further, certain transactions, such as age-restricted transactions, for example, prohibition on underage alcohol purchases or application of senior citizen discounts, are prohibited to certain categories of customer depending upon laws or merchant policies. In another example, transactions are restricted to consumers having a club membership.

Current applications require the consumer to perform actions to identify himself by providing user account identifiers or other data to the merchant system. Merchant system employees or clerks may have to ask customers for and obtain identification in these scenarios. Current applications do not provide for automatically identifying a user via facial recognition to determine whether the user is eligible to perform a restricted transaction without any action required by the user.

SUMMARY

Techniques herein provide computer-implemented methods to conduct a hands-free transaction with facial recognition of a user. In an example embodiment, a merchant system or other service provider system registers with an account management system. A user establishes an account with the account management system and transmits an image of himself to the account management system to establish a facial template associated with the user account. A user signs into the application via the user computing device and enters the location of the merchant system or service provider system. The user computing device receives a merchant beacon device identifier from the merchant beacon device and transmits the identifier to the account management system. The account management system transmits facial templates of all user whose computing device is in network range of the merchant beacon device and who are signed in to the application to a camera device installed at the merchant system location. The camera device captures a facial image of the user and identifies the user by comparing the captured facial image to the received facial templates. The camera device transmits an identity of the user to the point of sale device and the point of sale device transmits a request for user account information associated with the user identify to the account management system. The account management system receives the request for user account information and transmits the user account information associated with the user account associated with the identified user to the point of sale device. An operator of a merchant point of sale device or other device associated with the merchant system determines, based on information of the identified user associated with the user account, whether the user is qualified to perform a restricted transaction. If the operator determines that the user is eligible to perform the restricted transaction, the operator of the merchant point of sale device selects an account of the user for use in a transaction from one or more displayed accounts of the user. The merchant point of sale device transmits transaction details to the account management system, which generates a transaction authorization request to transmit to an issuer system associated with the user account selected for use in the transaction. The account management system receives an approval of the transaction authorization request and transmits a receipt to the merchant point of sale device.

In other example embodiments, the operator may initiate a command via the device associated with the service provider system to initiate the transaction. For example, the operator may initiate, via the device associated with the service provider system, a request for information to provide to the user. In another example, the operator may provide the user with access to a restricted area of a building by entering a command via the merchant device.

In certain other example aspects described herein, systems and computer program products to conduct a hands-free transaction with facial recognition of a user are provided.

These and other aspects, objects, features, and advantages of the example embodiments will become apparent to those having ordinary skill in the art upon consideration of the following detailed description of illustrated example embodiments.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

Overview

The example embodiments described herein provide computer-implemented techniques for conducting a hands-free transaction with facial recognition of a user.

In an example embodiment, a merchant system or service provider system registers with an account management system. The merchant system installs one or more merchant beacon devices, one or more merchant point of sale devices, and one or more merchant camera devices at a merchant system location. A user establishes an account with the account management system and downloads an application to a user computing device associated with and operated by the user. In an example, the user transmits an image of himself and/or an audio recording of himself to the account management system to establish a facial template and/or audio template associated with the user account. In another example, the user configures a challenge and response to associate with the user account, and the account management system receives the configuration of the challenge and response via the user computing device. For example, the challenge and response may comprise a question and answer. In this example, the question may read “What is your mother's maiden name?” and the answer may read “Smith.” In another example, the challenge and response may comprise a request for a password and a password.

The user enters a merchant system location and signs into the application via the user computing device. In another example, the user is already signed into the application via the user computing device before entering the location. The user computing device receives a merchant beacon device identifier from the merchant beacon device via a local wireless network at the location and transmits the identifier to the account management system via a network. For example, the user computing device may periodically scan for wireless network devices and may detect the merchant beacon device identifier broadcast from the merchant beacon device via the scan for wireless network devices. The account management system transmits facial templates to the camera device. For example, the account management system transmits all the facial templates that correspond to any users whose user computing devices are within network range of the merchant beacon device and/or who are signed into the application. The merchant camera device captures a facial image of the user and identifies the user by comparing the user's captured facial image to the facial templates received from the account management system. Alternatively, the user submits an audio recording to the account management system via the merchant point of sale device, which identifies the user based on comparing the received audio recording against audio templates for users. In yet another example, the merchant point of sale device operator identifies the user based on a user's response to a challenge by comparing a received challenge and response to the challenge and response associated with the user's account.

In an example, after identifying the user, the merchant point of sale device displays user information associated with the user's account management system account so that the merchant point of sale device operator can determine whether the user is eligible for a restricted transaction based on the displayed user information. The merchant point of sale device operator, in response to determining that the user is eligible for the transaction, selects a financial account associated with the user to process the transaction. The merchant point of sale device transmits transaction details to the account management system, which generates a transaction authorization request. The account management system transmits the transaction authorization request to an issuer system that corresponds to the selected financial account. The account management system receives an approval of the transaction authorization request and transmits a receipt to the merchant point of sale device.

In another example, after identifying the user, the merchant point of sale device displays user information associated with the user and the merchant point of sale device operator determines whether the user is eligible for a service based on the displayed user information. In this example, the merchant point of sale device operator, in response to determining that the user is eligible for the service, provides the user with access to the service. In certain example embodiments, in response to determining that the user is not eligible for a transaction and/or for a service, the merchant point of sale device operator informs the user that the user is not eligible for the respective transaction or service. The merchant point of sale device operator may further select or additional user interface objects on the interface of the merchant point of sale device to cancel a transaction and/or a service in accordance with determining that the user not eligible.

In other example embodiments described herein, one or more actions described herein as being performed by a merchant system, a merchant system operator, a merchant system point of sale device, a merchant beacon device may be performed by a service provider system, an operator associated with the service provider system, a computing device associated with the service provider system, and a beacon device associated with the service provider system, respectively. Likewise, one or more actions described herein as occurring at a merchant system location may occur at a service provider system location. An example merchant system may comprise a brick and mortar store location, a toll booth, a ticketing office, a supermarket, or other location where users may engage in transactions for goods or services with the merchant system. An example service provider system may comprise a restricted access building, restricted access location, a border crossing, a security gate, a service that provides restricted information to users, a customer service location, or other appropriate service provider system.

In an example embodiment, a merchant system registers with an account management system. A merchant system operator installs an application on a merchant point of sale device. In another example, the merchant system operator installs the application on a plurality of merchant point of sale devices at a merchant system location. A merchant beacon device receives a beacon identifier code from an account management system. For example, the merchant system operator installs one or more merchant beacon devices at the merchant system location. In another example embodiment, the merchant beacon device is a part of or combined within the merchant point of sale device. The merchant beacon device broadcasts the merchant beacon identifier code via wireless communication at the merchant system location. The merchant system operator installs a merchant camera device at the merchant system location to correspond to the merchant point of sale device. In another example, a plurality of merchant camera devices are installed at the merchant system location, each merchant camera device corresponding to a particular merchant point of sale device. In yet another example, a particular merchant camera device may correspond to two or more particular merchant point of sale devices. The account management system receives a camera device identifier and associates it with a corresponding beacon identifier code of the merchant beacon device.

In an example embodiment, the user registers with an account management system. For example, the user accesses an account management system website via a user computing device operated by the user. The user registers with the account management system and downloads an application onto the user computing device. In an example embodiment, the account management system establishes a facial template associated with the user account. For example, the application displays a request for the user to capture a facial image via the user computing device. The user selects an option to capture a facial image. The application activates a camera on the user computing device and the users captures a facial image of himself. In another example embodiment, the user selects a facial image previously saved on the user computing device and transmits the image to the account management system. The account management system receives the facial image. The account management system creates a facial template associated with the user account based on the received facial image. The account management system deletes the received facial image. In another example embodiment, the account management system establishes a audio template associated with the user account. The application requests and receives user audio via the user computing device. The application creates an audio template associated with the user account based on the received audio of the voice of the user. The account management system deletes the received audio of the voice of the user.

The user signs in to an application on the user computing device. The user carries the user computing device within a threshold distance of a merchant beacon device at the merchant system location. The user computing device receives a merchant beacon identifier code broadcasted by the merchant beacon device. The user computing device transmits the received merchant beacon identifier code and a user account identifier to the account management system. The account management system receives the merchant beacon identifier code and the user account identifier, extracts a facial template associated with the user account identifier, and identifies a merchant camera device associated with the merchant beacon device identifier.

The account management system transmits a facial template of the identified user to the merchant camera device associated with the merchant beacon device identifier. For example, a facial template associated with the identified user's account is transmitted to the merchant camera device. The merchant camera device receives the facial template of the user, and adds the facial template of the user to a current customer log. The merchant camera device periodically updates the current customer log based on updates received from the account management system. For example, the account management system transmits, to the merchant camera device, a subsequent facial template of a subsequent user that is operating a computing device that is signed into the application and enters a threshold distance of a merchant beacon device required to establish a wireless network connection. In this example, the account management system receives the merchant beacon device identifier transmitted by the computing device and transmits a facial template of the subsequent user to the merchant camera device. In another example, in response to detecting that the user computing device associated with a user in the current customer log is no longer maintaining a network connection with the merchant beacon device, is no longer observing the merchant beacon device, or is no longer signed in to the application, the account management system transmits a notice that a user has left a merchant location to the merchant camera device. In this example, the merchant camera device deletes the indicated user from the current customer log.

In another example, instead of transmitting the facial template to the merchant camera device, the account management system transmits the facial template to the merchant point of sale device associated with the merchant beacon device identifier. For example, a facial template associated with the identified user's account is transmitted to the merchant point of sale device. The merchant point of sale device receives the facial template of the user, and adds the facial template of the user to a current customer log. The merchant point of sale device periodically updates the current customer log based on updates received from the account management system. For example, the account management system transmits, to the merchant point of sale device, a subsequent facial template of a subsequent user that is operating a computing device that is signed into the application and enters a threshold distance of a merchant beacon device required to establish a wireless network connection. In this example, the account management system receives the merchant beacon device identifier transmitted by the computing device and transmits a facial template of the subsequent user to the merchant point of sale device. In another example, in response to detecting that the user computing device associated with a user in the current customer log is no longer maintaining a network connection with the merchant beacon device, is no longer observing the merchant beacon device, or is no longer signed in to the application, the account management system transmits a notice that a user has left a merchant location to the merchant point of sale device. In this example, the merchant point of sale device deletes the indicated user from the current customer log.

The user approaches a merchant point of sale device. The merchant point of sale device operator totals items of the user for purchase. The merchant point of sale device operator asks the user to select a payment option. The user directs the merchant point of sale device operator to initiate a transaction via the application. The merchant point of sale device operator selects an option on the merchant point of sale device to initiate a transaction using the application. The merchant point of sale device transmits a request to identify the user to the merchant camera device via the account management system or via the local wireless network at the merchant location. In this example, the account management system communicates with both the merchant camera device and the merchant point of sale device.

In another example embodiment, the merchant point of sale device receives an indication from the merchant camera device that the user has been identified and the merchant point of sale device displays an option for the user to initiate a transaction using the application. For example, the merchant point of sale device may receive an indication that the user has been identified directly from the merchant camera device over a network. In another example, the merchant camera device transmits an indication that the user has been identified to the account management system. The account management system transmits the indication that the user has been identified to the merchant point of sale device. In these example embodiments, the merchant point of sale device operator, in response to the merchant point of sale device displaying an option to initiate a transaction using the application, asks the user whether the user would like to initiate a transaction using the application. In these example embodiment, the user directs the merchant point of sale device operator to initiate the transaction via the application and the merchant point of sale operator selects the corresponding option on the merchant point of sale device user interface.

In other example embodiments, instead of a merchant point of sale device, the user approaches a computing device associated with a service provider system. For example, the user approaches a computing device associated with a security gate and the computing device transmits a request to identify the user to a camera device or to the account management system. In an example embodiment, the computing device may be part of a security system or a system that provides restricted services or information to users.

The merchant camera device at the merchant system location captures video of the user. For example, the user is positioned in front of the point of sale device and the merchant camera device is positioned to be able to capture a video of the user's face. In an example embodiment, the merchant camera device starts capturing video of the user only when the camera device receives a request to identify the user. For example, the merchant camera device receives a request to identify the user from the account management system or from the merchant point of sale device. In another example embodiment, the merchant camera device starts capturing video when the merchant camera device receives an indication from the account management system that a user computing device associated with the user has established a network connection with the merchant beacon device or has otherwise received a beacon identifier code from the merchant beacon device. In this example embodiment, the merchant camera device does not capture video when there are no users with associated user computing devices within network range of the merchant beacon device.

The merchant camera device extracts a facial image of the user from the captured video and generates a facial template from the captured facial image. The merchant camera device deletes the captured video and extracted facial image. The merchant camera device retrieves facial templates from the current customer log. For example, the current customer log comprises a list of users and associated facial templates for users associated with computing devices that have currently established a network connection with a merchant beacon device at the merchant system location. In an example embodiment, the current customer log comprises volatile or transient memory. For example, the current customer log is not saved and user information is added or deleted from the current customer log as computing devices associated with respective users enter or leave a network range of the merchant beacon device.

The merchant camera device compares the generated facial template from the extracted facial image to facial templates from the current customer log. The merchant camera device is able to identify the user if there is a match between a facial template from the current customer log and the generated facial template. The merchant camera device is unable to identify the user if there is no match between a facial template from the current customer log and the generated facial template. If the merchant camera device is able to identify the user, the merchant camera device notifies the account management system of the identity of the user. In another example embodiment, if the merchant camera device is able to identify the user, the merchant camera device notifies the merchant point of sale device of the identity of the user.

If the merchant camera device is unable to identify the user based on facial recognition, the merchant camera device notifies the account management system that the user cannot be identified based on facial recognition. In an example embodiment, if the user cannot be identified based on facial recognition, the account management system identifies the user based on audio recognition. In another example embodiment, the account management system does not identify users based on audio recognition. In an example embodiment, if the account management system identifies users based on audio recognition, the account management system retrieves audio templates corresponding to users from the current customer log. The account management system transmits a request to the merchant system point of sale device to record an audio of the user. The merchant system point of sale device displays a request for the user to record audio, records a voice input of the user, and transmits the voice input to the account management system. The account management system compares the received voice input against the retrieved audio templates corresponding to users from the current customer log. The account management system is able to identify the user if there is a match between an audio template from the current customer log and the received voice input of the user. The account management system is unable to identify the user if there is no match between an audio template from the current customer log and the received voice input of the user.

If the account management system is unable to identify the user based on voice recognition, the merchant point of sale device operator is notified by the account management system to issue a challenge to the user. The user provides a challenge response and the merchant point of sale operator inputs the response into the merchant point of sale device. The merchant point of sale device displays potential users based on the challenge response. For example, the merchant point of sale device transmits the response to the account management system and the account management system accesses a database comprising a list or table that associates challenges with corresponding responses and users. In this example, the account management system identifies the user by correlating the challenge and the response to identify one or more users in the database. In this example, the account management system transmits the one or more identified users to the merchant point of sale device. In this example, the merchant point of sale device displays the one or more identified users to the merchant point of sale device operator. The merchant point of sale device operator selects a user. In an example, the merchant point of sale device operator may compare a visual image or name of the user displayed on the user computing device to the visual appearance of the current customer at the merchant point of sale device and/or documentation presented by the user to the merchant point of sale operator. In an example, the merchant point of sale device transmits the identity of the user identified by the merchant point of sale operator.

The merchant point of sale device displays information associated with the identified user account to the merchant point of sale device operator. In an example embodiment, the information associated with the user account comprises a list of goods or services for which the user is eligible and/or ineligible to purchase or receive. For example, the list of goods or services for which the user is eligible may list alcohol purchases, tobacco purchases, lottery tickets, special promotions, and/or other restricted goods or services which the user is allowed to purchase or to which the user is allowed access. In another example, the information associated with the user account comprises demographic information, for example, information identifying an age or age group of the user. For example, the information associated with the user account identifies the user as being in the 21-or-older, 18-or-older, or 60-and-older age group. In an example embodiment, the merchant point of sale device operator determines whether the user is eligible for a transaction or other service based on the information associated with the user account of the identified user. For example, the merchant point of sale device operator determines that the user is eligible for a senior discount for consumers 60 years of age or older based on an identification of the age group of the user comprising the 60-and-older age group in the information associated with the user account. In an example, the merchant point of sale device operator determines whether the requested good or service corresponds to an allowed or prohibited item listed in the information associated with the identified user account. In another example, the merchant point of sale device operator compares information comprising demographic information associated with the user from the user account against one of more of a merchant system policy or law associated with city, state, county, country, or other legal jurisdiction associated with the merchant system location to determine whether the user may purchase or receive the desired good or service.

In an example embodiment, if the merchant point of sale device operator determines that the user is not eligible to purchase or receive a desired good or service, the operator informs the user that the user is ineligible to purchase or receive the good or service. In certain example embodiments, the merchant point of sale device operator may actuate one or more objects on the user interface of the merchant point of sale device to cancel a current transaction, request additional information, or other ongoing procedure for acquiring goods or services operating on the merchant point of sale device. For example, the merchant point of sale device operator selects an option on the user interface that reads “cancel current transaction.” In another example, a service provider system operator associated with a security gate denies entry to the user based on information associated with the identified user's account by actuating one or more user interface objects on the computing device associated with the service provider system.

In an example embodiment, if the merchant point of sale device operator determines, based on the information associated with the user account, that the user is eligible for the desired good or service, the merchant point of sale device operator selects an option on the user interface of the merchant point of sale device indicating that the user is eligible to purchase or receive the good or service, and the merchant point of sale device displays one or more accounts of the identified user. For example, after receiving the identity of the user from the merchant camera device, receiving the identity of the user from the merchant point of sale device, or identifying the user, the account management system transmits the information associated with the account of the identified user. In this example, the account management system, in response to the merchant point of sale device operator selecting the option via the user interface of the merchant point of sale device indicating that the user is eligible to purchase or receive the good or service, receives a request from the merchant point of sale device for user account information, and transmits information associated with one or more payment accounts of the identified user. The merchant point of sale device may display the one or more payment or financial accounts of the user on the user interface of the merchant point of sale device. The merchant point of sale device operator selects a user account for transaction via the user interface and provides an input to the merchant point of sale device to confirm the transaction with permission of the user. The merchant point of sale device transmits transaction details to the account management system. In an example embodiment, the merchant point of sale device operator may select or merchant point of sale device may automatically apply one or more offers or discounts to the transaction based on the information associated with the account of the identified user. For example, transaction details may comprise a total amount of the transaction, a selected user account for use in the transaction, an account of the merchant for use in the transaction, and other useful or relevant information. The account management system transmits a transaction authorization request to an issuer system that corresponds to the selected financial account. For example, the issuer system is associated with the user financial account selected for use in the transaction. The issuer system approves the transaction authorization request and transmits a transaction authorization approval to the account management system. The account management system transmits a transaction receipt to the merchant point of sale device.

In another example embodiment, the user approaches a computing device associated with a service provider system. For example, the user approaches a computing device associated with a security gate, and the computing device associated with a security gate transmits a request to identify the user to a camera device or to the account management system. In an example embodiment, the computing device may be part of a security system or a system which provides restricted services or information to users. In this example embodiment, if the computing device operator determines, based on the information associated with the user account, that the user is eligible for the desired good or service, the computing device operator selects an option on the user interface of the computing device indicating that the user is eligible to receive the service. In an example, receiving the service comprises receiving permission to access sensitive information. In another example, receiving the service comprises receiving access to open or otherwise pass through a security gate or barrier.

By using and relying on the methods and systems described herein, the account management system, the merchant camera device, the merchant beacon device, the user computing device, and the merchant point of sale device enable the user to conduct a transaction with the merchant system without the user having to interact with the user computing device, produce identity documents, or physical payment cards, as required in current technology. As such, the systems and methods described herein may reduce the inputs required by the user on the user computing device and the inputs required by the merchant point of sale device operator to identify the user.

Example System Architecture

Turning now to the drawings, in which like numerals indicate like (but not necessarily identical) elements throughout the figures, example embodiments are described in detail.

FIG. 1 is a block diagram depicting a system 100 for conducting a hands-free transaction with facial recognition of a user 101, in accordance with certain example embodiments. As depicted in FIG. 1, the system 100 includes network computing devices 110, 130, 140, 150, and 160 that are configured to communicate with one another via one or more networks 120. In some embodiments, a user associated with a device must install an application and/or make a feature selection to obtain the benefits of the techniques described herein.

In example embodiments, the network 170 can include a local area network (“LAN”), a wide area network (“WAN”), an intranet, an Internet, storage area network (“SAN”), personal area network (“PAN”), a metropolitan area network (“MAN”), a wireless local area network (“WLAN”), a virtual private network (“VPN”), a cellular or other mobile communication network, Bluetooth, Bluetooth low energy, NFC, or any combination thereof or any other appropriate architecture or system that facilitates the communication of signals, data, and/or messages. Throughout the discussion of example embodiments, it should be understood that the terms “data” and “information” are used interchangeably herein to refer to text, images, audio, video, or any other form of information that can exist in a computer-based environment.

Each network computing device 110, 130, 140, 150, and 160 comprises a device having a communication device capable of transmitting and receiving data over the network 170. For example, each network computing device 110, 130, 140, 150, and 160 can comprises a server, desktop computer, laptop computer, tablet computer, a television with one or more processors embedded therein and/or coupled thereto, smart phone, handheld computer, personal digital assistant (“PDA”), or any other wired or wireless, processor-driven device. In the example embodiment depicted in FIG. 1, the network computing devices 110, 130, 140, 150, and 160 are operated by users 101, merchant beacon device 120 operators, merchant point of sale (“POS”) device 130 operators, merchant camera device 140 operators, issuer system 150 operators, and account management system 160, respectively.

An example user computing device 110 comprises an antenna 111, a Wi-Fi controller 112, an application 113, a user interface 115, a data storage unit 116, a camera 117, a web browser 118, and a communication application 119.

In an example embodiment, the antenna 111 is a means of communication between the user computing device 110 and a merchant beacon device 120. In an example embodiment, a Wi-Fi controller 112 outputs through the antenna 111 a radio signal, or listens for radio signals from the merchant beacon device 120. In another example embodiment a Bluetooth controller or a near field communication (“NFC”) controller is used. In an example embodiment, the Wi-Fi controller 112 outputs through the antenna 111 a radio signal, or listens for radio signals from the payment card device 120.

In an example embodiment, the Wi-Fi controller 112 is capable of sending and receiving data, performing authentication and ciphering functions, and directing how the user computing device 110 will listen for transmissions from the merchant beacon device 120 or configuring the user computing device 110 into various power-save modes according to Wi-Fi-specified procedures. In another example embodiment, the user computing device 110 comprises a Bluetooth controller or an NFC controller capable of performing similar functions. An example Wi-Fi controller 112 communicates with the application 113 and is capable of sending and receiving data over a wireless, Wi-Fi communication channel. In another example embodiment, a Bluetooth controller 112 or NFC controller 112 performs similar functions as the Wi-Fi controller 112 using Bluetooth or NFC protocols. In an example embodiment, the Wi-Fi controller 112 activates the antenna 111 to create a wireless communication channel between the user computing device 110 and the merchant beacon device 120.

From block 360, the method 210 proceeds to block 220 of FIG. 2.

Returning to FIG. 2, in block 220, the user 101 registers with the account management system 160. The method for registering, by a user 101, for an account with an account management system 160 and creating a user 101 account is described in more detail hereinafter with reference to the method 220 described in FIG. 4.

FIG. 4 is a block diagram depicting a method 220 for registering, by a user 101, for an account with an account management system 160 and creating a user 101 account, in accordance with certain example embodiments. The method 220 is described with reference to the components illustrated in FIG. 1.

In block 410, the user 101 accesses the account management system website 169. For example, the user 101 accesses the account management system 160 via the web browser 118 of the user computing device 110. In another example, the user 101 may otherwise contact the account management system 160 to register for a user 101 account.

In block 420, the user 101 registers with the account management system 160. The user 101 may obtain a user account number, receive the appropriate applications and software to install on the user computing device 110, request authorization to participate in hands-free payment processing, or perform any action required by the account management system 160. The user 101 may utilize the functions of the user computing device 110, such as the user interface 115 and the web browser 118, to register and configure a user 101 account. In an example embodiment, the user 101 may enter payment account information associated with one or more user 101 accounts, for example, one or more credit accounts, one or more bank accounts, one or more stored value accounts, and/or other appropriate accounts into the user 101 account maintained by the account management system 160. The user 101 may also enter contact information comprising one or more addresses, telephone numbers, email addresses, locations, or other information identifying contact information of the user 101. In another example, the user 101 may enter demographic information of the user 101, for example, an age of the user 101 or a birthdate of the user 101, In yet another example, the user 101 may enter one or more club memberships or program memberships of the user 101. For example, the user 101 may enter an account number associated with a merchant system loyalty program membership.

In block 430, the user 101 downloads the application 113 onto the user computing device 110. In an example embodiment, the application 113 operating on the user computing device 110 is able to communicate with the account management system 160 over the network 170. In an example embodiment, the user 101 may configure user 101 account settings or add, delete, or edit payment account information via the application 113. In an example embodiment, the user 101 may select an option to enable or disable the permission of the account management system 160 to process hands free transactions. For example, a hands free transaction comprises a transaction wherein the user 101 does not need to interact with the user computing device 110 or requires minimal user 101 interaction with the user computing device 110 to initiate a transaction with the merchant system.

In block 440, the account management system 160 establishes a facial template associated with the user 101 account. The method for establishing a facial template associated with a user 101 account is described in more detail hereinafter with reference to the method 440 described in FIG. 5.

FIG. 5 is a block diagram depicting a method 440 for establishing a facial template associated with a user 101 account, in accordance with certain example embodiments. The method 440 is described with reference to the components illustrated in FIG. 1.

In block 510, the application 113 displays a request for the user 101 to capture a facial image via the user computing device 110. In an example embodiment, the application 113 displays the request via the user interface 115. In an example, the user interface 115 may display a request that reads, “to enable hands free transactions, we need an image of your face. Would you like submit a facial image now?” In this example, the user 101 may select an option to take a current picture or may otherwise select a picture stored on the user computing device 110.

In block 520, the user 101 selects an option to capture a facial image. For example, the user 101 actuates an object on the user interface 115 that reads, “yes, I would like to take a picture now.”

In block 530, the application 113 activates the camera 117 on the user computing device 110 and the user 101 captures a facial image of himself. In an example embodiment, the user computing device user interface 115 may display a live camera feed of the user 101 to aid the user 101 in aligning the user's 101 face to take the facial image. In an example embodiment, the application 113 may display on the user computing device 110 a box or other perimeter on the user interface 115 within which the user 101 should align his face to take a picture of a required size predetermined by the account management system 160. In an example embodiment, the user 101 may actuate an object on the user interface 115 to capture the image. In this example embodiment, in response to the user actuating the object on the user interface 115, the camera 117 receives a command from the application 113 to capture an image of the user 101. In another example embodiment, the camera 117 receives a command from the application 113 to capture a plurality of images of the user 101 as the user 101 moves the camera around the user's 101 face. For example, each of the plurality of images of the user 101 may correspond to a particular pose of the user's 101 face. An example facial image may comprise a digital image of the face of a user 101. In an example embodiment, the account management system 160 may establish guidelines for users 101 in submitting facial images. For example, the application 113 may direct the user 101 to remove any hats, head coverings, glasses, or other objects or accessories that may occlude regions of the user's 101 face so that application 160 may receive a complete depiction of the user's 101 face.

In an example embodiment, the user computing device 110 determines if the captured facial image is a valid facial image or an invalid facial image. For example, a valid facial image complies with guidelines predetermined by the account management system 160 and an invalid facial image does not comply with one or more of the guidelines. For example, if the user computing device 110 captures a facial image that comprises incorrect dimensions, if part or all of the user's 101 face is occluded, or if the image is too dark or too bright, the user computing device 110 rejects the invalid facial image and displays a request directing the user 101 to capture a subsequent facial image. In this example, the user 101 captures a subsequent facial image via the user computing device 110, and the user computing device 110 transmits the subsequent facial image to the account management system 160 via the network 170.

In block 540, the account management system 160 receives the facial image. In another example embodiment, the account management system 160 receives a plurality of facial images of the user 101. For example, the application 113 transmits the one or more facial images of the user 101 to the account management system 160 via the network 170. In an example embodiment, the account management system 160 associates the received one or more facial images with the user 101 account. For example, the account management system 160 is able to identify the user 101 account to associate with the received one or more images because the user 101 is currently logged in to the application 113 on the user computing device 110 at the time the one or more facial images are transmitted to the account management system 160. In certain example embodiments, the account management system 160 determines if the received facial image is a valid facial image or an invalid facial image. For example, a valid facial image complies with all guidelines predetermined by the account management system 160 and an invalid facial image does not comply with one or more of the guidelines. For example, if a user 101 submits a facial image that comprises incorrect dimensions, if part or all of the user's 101 face is occluded, or if the image is too dark or too bright, the account management system 160 rejects the invalid facial image and transmits a request to the user computing device 110 directing the user 101 to capture a subsequent facial image to transmit to the account management system 160. In this example, the user computing device 110 receives and displays the request, the user 101 captures a subsequent facial image via the user computing device 110, and the user computing device 110 transmits the subsequent facial image to the account management system 160 via the network 170.

In block 550, the account management system 160 creates a facial template associated with the user 101 account based on the received facial image. In another example embodiment, the account management system 160 generates a corresponding facial template for each of a plurality of received facial images associated with the user 101 account. In an example, the facial template is of a predetermined size, for example, a 128-byte facial template. In an example, the account management system 160 generates a facial template comprising a computer code representation of the digital facial image. For example, the facial template may describe key features of the facial image of the user 101, such as shape, color, line, value, space, form, texture, or other useful or relevant feature of the image or of particular regions of the image. In an example, the facial template is generated by processing the facial image through a convolutional neural network. In an example embodiment, the account management system 160 stores the generated facial template associated with the user 101 in a data storage unit 166 associated with the account management system 160. For example, the account management system 160 database may comprise a table or other means by which it correlates each user 101 account identifier with an associated facial template of the user 101.

In another example embodiment, after the user computing device 110 captures one or more facial images of the user 101, the user computing device 110 generates one or more facial templates corresponding to one or more of the one or more captured facial images of the user 101. In this example embodiment, the user computing device 110 transmits the one or more generated facial templates to the account management system 160 over the network 170.

In block 560, the account management system 160 deletes the received facial image. For example, the account management system 160 only uses a facial template comprising a computer code representation of the facial image of the user 101. In another example, the account management system 160 saves the received facial image for future processing. For example, the account management system 160, at a later time, updates a facial template generation algorithm and generates an updated facial template corresponding to the saved facial image.

From block 560, the method 440 proceeds to block 450 in FIG. 4.

Returning to block 450, in FIG. 4, the account management system 160 establishes an audio template associated with the user 101 account. The method for establishing an audio template associated with a user 101 account is described in more detail hereinafter with reference to the method 450 described in FIG. 6.

FIG. 6 is a block diagram depicting a method 450 for establishing an audio template associated with a user 101 account, in accordance with certain example embodiments. The method 450 is described with reference to the components illustrated in FIG. 1.

In block 610, the application 113 displays a request for the user 101 to capture an audio recording of the user's 101 voice via the user computing device 110. In an example embodiment, the application 113 displays the request via the user interface 115. In an example, the user interface 115 may display a request that reads, “to enable hands free transactions, we need recording of your voice. Would you like submit a audio recording now?” In this example, the user 101 may select an option to submit a live audio recording or may otherwise select a pre-recorded audio recording of the user 101 stored on the user computing device 110.

In block 620, the user 101 selects an option to capture an audio recording. For example, the user 101 actuates an object on the user interface 115 that reads, “yes, I would like to submit a audio recording now.”

In block 630, the application 113 activates an audio component (not depicted) on the user computing device 110 and the user 101 captures an audio of the user's 101 voice. In an example embodiment, the user computing device user interface 115 may display guidelines received from the account management system 160 to aid the user 101 in submitting an audio recording. For example, the application 113 may display directions for the user 101 to record the user's 101 voice saying the user's 101 name or a sample dictation. In another example, the application 113 directs the user 101 to capture an audio recording to establish a voice password that can be used in hands-free transactions of the user 101. In an example embodiment, the user 101 may actuate an object on the user interface 115 to capture or record a live audio recording. In this example embodiment, in response to the user actuating the object on the user interface 115, the audio component receives a command from the application 113 to capture an audio recording of the user 101. In an example embodiment, the account management system 160 may establish guidelines for users 101 in submitting audio recordings. For example, the application 113 may direct the user 101 to submit an audio recording no longer than a predefined maximum length of duration. For example, the audio recording must be no longer than five seconds. In another example, the application 113 may direct the user 101 submit an audio recording lasting a predefined length of time, for example, an audio recording lasting five seconds. In an example embodiment, after the user 101 initiates an audio recording by actuating an object of the user interface 115, the application 113 transmits a command to the audio component to stop recording the user's 101 voice after the predefined length of time or predefined maximum length of time has expired.

In block 640, the account management system 160 receives an audio recording of the voice of the user 101. For example, the application 113 or audio component transmits the audio recording to the account management system 160 over the network 170. In another example, the application 113 retrieves an audio recording selected by the user 101 and saved in the data storage unit 116 and transmits the retrieved audio recording to the account management system 160 over the network 170.

In block 650, the account management system 160 creates an audio template associated with the user's 101 voice based on the received audio of the voice of the user. In an example, the audio template is of a predetermined size. In an example, the account management system 160 generates an audio template comprising a computer code representation of the user's 101 audio recording. For example, the audio template may describe key features of the audio recording of the user 101, such as the intonation of the user's 101 voice or other acoustic features of the user's 101 voice such as volume or pitch. In an example embodiment, the account management system 160 stores the generated audio template associated with the user 101 in a data storage unit 166 associated with the account management system 160. For example, the account management system 160 database may comprise a table or other means by which it correlates each user 101 account identifier with an associated audio template of the user 101

In block 660, the account management system 160 deletes the received audio of the voice of the user 101. In an example embodiment, the account management system 160 deletes the received audio recording of the user 101 to protect the privacy of the user 101. For example, the account management system 160 only uses a audio template comprising a computer code representation of the audio recording of the user 101.

From block 660, the method 440 proceeds to block 225 in FIG. 2.

Returning to block 225, in FIG. 2, the user 101 enters the merchant system location.

In block 230, the user computing device 110 receives a merchant beacon device 120 identifier. The method for receiving, by a user computing device 110, a merchant beacon identifier code broadcast from a merchant beacon device 120 is described in more detail hereinafter with reference to the method 230 described in FIG. 7.

FIG. 7 is a block diagram depicting a method 230 for receiving, by a user computing device 110, a merchant beacon identifier code broadcast from a merchant beacon device 120, in accordance with certain example embodiments. The method 230 is described with reference to the components illustrated in FIG. 1. In another example embodiment, the user computing device 110 receives a beacon identifier code broadcasted by a beacon device at the service provider system location. The method of receiving a beacon identifier code, using the user computing device 110, from the beacon device at the service provider system location may be similar to the method 230 for receiving, by a user computing device 110, a merchant beacon identifier code broadcast from a merchant beacon device 120.

In block 710, the user 101 signs in to the application 113 on the user computing device 110. In an example embodiment, the user 101 may have a username and password associated with the user 101 account maintained by the account management system 160. In an example embodiment, the user 101 opens the application 113 on the user computing device 110 and enters a username and/or password via the user interface 115 to sign in to the application 113. In an example embodiment, when the user 101 is signed in to the application 113, the application is able to communicate with the account management system 160 over the network 170. In this example embodiment, when the user 101 is not signed in to the application 113, the application does not communicate with the account management system 160 even if the a network 170 connection is available. In an example embodiment, the user 101 may sign out of the application 113 at any time by actuating one or more objects on the user interface 115 of the user computing device 110. In an example embodiment, after signing in to the application 113, the user 101 configures one or more user 101 account settings, add, edit, or delete user 101 payment account information, and/or change user 101 preferences. In certain example embodiments, a user 101 may be required to make a feature selection to obtain the benefits of the techniques described herein. For example, the user 101 may have to enable one or more user 101 account settings to enable hands free transactions according to the methods described herein.

In an example embodiment, application 113 may provide options, data, configurable alerts, and other suitable features to the user 101. For example, the application 113 may comprise a listing of merchant systems and merchant locations that participate in hands free payment transactions according to one or more of the methods described herein. The listing may be updated periodically from the account management system 160. The application 113 may notify the user 101 when the user 101 is within a configured vicinity of a participating merchant system. The application 113 may provide the user 101 with options to update payment preferences. The application 113 may provide the user 101 with a listing of recent transactions. The application 113 may provide any other suitable information to the user 101.

In block 720, the user 101 carries the user computing device 110 within a threshold distance of the merchant beacon device 120 at the merchant system location, for example, within five meters of the merchant beacon device 120. In an example embodiment, the user 101 enters a location of the merchant system carrying the user computing device 110 in a pocket or a bag, in the hands of the user 101, or in any suitable manner. The location of the merchant system may be a store location, a kiosk location, or any suitable physical location of a merchant system. In another example embodiment, a merchant POS operator 102 may be mobile and arrive at a location of the user 101. For example, the merchant system may be a restaurant and the merchant POS device operator 102 may be a delivery person possessing a portable merchant POS device 130.

In certain example embodiments, the application 113 may alert the user 101 when the user 101 is in the vicinity of a merchant system that accepts hands-free payments. The alert may be provided via a message on the user computing device 110, via an email or a text, or in any suitable manner. In an example embodiment, the alert may be based on the location of the user 101 as determined by a global positioning system (“GPS”) component (not depicted) resident on the user computing device 110 or as determined via cellular tower triangulation. For example, the application 113 accesses the GPS data from the GPS component and compare the GPS location to a list of locations of merchant systems that accept hands free payments. For example, the application 113 comprises a list or accesses a list maintained by the account management system 160 of merchant system locations that accept hands free payments. If a match results from the comparison, then an alert is generated and provided to the user 101. The match may result if the user 101 is within a configured distance of a qualified merchant system location. In an example embodiment, the alerts may be configured to alert in any suitable manner. In an example, the alerts may be combined in commercially dense environments or the alerts may be presented individually. In another example, the alerts may be configured to only alert the user 101 a configured number of times. For example, the alert may be presented three times, but upon a fourth instance, the alert is not presented. The alerts may be presented as a notification with an audible alert, a vibration, a popup alert on the user interface 115 of the user computing device 110, or other suitable alert.

In block 730, the user computing device 110 receives a merchant beacon identifier code broadcasted by the merchant beacon device 120. The user computing device 110 recognizes a merchant beacon device 120 via wireless communication at the location of the merchant system. The user computing device 110 may be configured to search for beacons or other wireless signals. In an example embodiment, the user computing device 110 and the merchant beacon device 120 establish a Wi-Fi wireless network 170 connection. In other example embodiments, the user computing device 110 and the merchant beacon device 120 establish a Bluetooth, BLE, NFC, or other appropriate network 170 connection.

For example, the account management system 160 receives the merchant beacon identifier code and the user 101 account identifier over the network 170. The user computing device 110 may compare the data from the merchant beacon identifier code to a database of merchant beacon identifier code data and merchant camera device identifier data to determine an identity of the merchant system and merchant camera device 140 associated with the merchant beacon identifier code and/or to verify the authenticity of the beacon.

From block 750, the method 230 proceeds to block 240 in FIG. 2.

Returning to FIG. 2, in block 240, the merchant camera device 140 receives a facial template for each user 101 within range of the merchant beacon device 120. The method for receiving, by a merchant camera device 140, a facial template for each user 101 in range of the merchant beacon device 120 is described in more detail hereinafter with reference to the method 240 described in FIG. 8.

FIG. 8 is a block diagram depicting a method 240 for receiving, by a merchant camera device 140, a facial template for each user 101 in range of the merchant beacon device 120, in accordance with certain example embodiments. The method 240 is described with reference to the components illustrated in FIG. 1. In another example embodiment, a camera device installed at a service provider system location receives a facial template for each user 101 in range of a service provider system beacon device. The method for receiving, by a camera device at a service provider system location, a facial template for each user 101 in range of a service provider system beacon device may be similar to the method 230 for receiving, by a merchant camera device 140, a facial template for each user 101 in range of the merchant beacon device 120.

In block 810, the account management system 160 extracts a facial template associated with the user 101 account identifier. In an example embodiment, the account management system 160 accesses a database comprising stored facial templates of a plurality of users 101 with corresponding user 101 account identifiers for each user 101 to identify the facial template associate with the user 101 account identifier. For example, this database is stored in the data storage unit 166.

In block 820, the account management system 160 identifies a merchant camera device 120 associated with the merchant beacon device 120 identifier. In an example embodiment, the account management system 160 recognizes that the merchant beacon identifier code is associated with the account management system 160 and a particular merchant camera device 140 at the merchant system location. In an example embodiment, the account management system 160 recognizes that the merchant beacon identifier code is associated with a plurality of merchant camera devices 140 installed at a particular merchant location. In this embodiment, the account management system 160 identifies the plurality of merchant camera devices 140.

In block 830, the account management system 160 transmits the facial template of the identified user 101 to the identified merchant camera device 140 associated with the merchant beacon device 120 identifier.

In another example embodiment, a camera device at a service provider system location receives notification from the account management system 160 as users 101 enter or leave a network range of a beacon device located at a location of the service provider system. The method for receiving, by the camera device at the service provider system location, notification from the account management system 160 as users 101 enter or leave a network range of a beacon device located at a location of the service provider system may be similar to the method 860 for receiving, by a merchant camera device 140, notification from an account management system 160 as users 101 enter or leave a network range of a merchant beacon device 120.

In block 910, the merchant camera device 140 is notified by the account management system 160 as users 101 that is signed into a payment account enters or leaves the network range of the merchant beacon device 120. For example, as previously discussed, when a user 101 carrying a user computing device 110 enters a threshold distance from a merchant beacon device 120, the merchant beacon device 120 or the user computing device 110 of the user 101 are able to detect the other device and establish a wireless network 170 connection between the two devices at the merchant system location. In this example, the merchant beacon device 120 transmits the merchant beacon identifier code corresponding to the merchant beacon device 120 over the wireless network 170 to the user computing device 110. For example, the merchant beacon device 120 transmits the merchant beacon identifier code to the user computing device 110 via a Wi-Fi, Bluetooth, BLE, or NFC wireless communication network 170. In this example, the user computing device 110 periodically retransmits the received merchant beacon identifier code to the account management system 160 along with a user 101 account identifier identifying the user 101. In an example, if the user computing device 110 does not retransmit the received merchant beacon device 120 identifier code within a certain threshold period of time after previously retransmitting the identifier code, the account management system 160 may determine that the user computing device 110 has left the merchant system location and/or the merchant point of sale device 130 located in proximity to the merchant beacon device 120.

In block 920, the account management system 160 determines whether a new user 101 is in range of the merchant beacon device 120. For example, if the account management system 160 receives a new user 101 account identifier in addition to the same merchant beacon identifier code, the account management system 160 may determine that a new user 101 is in range of the merchant beacon device 120. In this example, the account management system 160 may infer that the new user 101 has entered the merchant location based on receipt of the new user 101 account identifier. In another example, if the account management system 160 does not receive any new user 101 account identifiers along with the same merchant beacon identifier code within a threshold length of time, the account management system 160 may determine that no new users 101 have entered the network 170 range of the merchant beacon device 120.

If a new user 101 is in range of the merchant beacon device 120, the method 860 proceeds to block 830 in FIG. 8. For example, the account management system 160 receives a new user 101 account identifier in addition to the same merchant beacon identifier code. In this example, the account management system 160 infers that the new user 101 has entered the merchant location based on receipt of the new user 101 account identifier and the same merchant beacon identifier code as previously received from the first user 101.

Returning to FIG. 8, in block 810, the account management system 160 extracts a facial template associated with the new user 101 account identifier. In an example embodiment, the account management system 160 transmits the facial template to the appropriate one or more merchant camera devices 140 and the one or more merchant camera devices 140 add the new user's 101 facial template to the current customer log according to the example method previously described in method 240 in FIG. 8.

Returning to FIG. 9, in block 920, if there is a not a new user 101 in range of the merchant beacon device 120, the method 860 proceeds to block 930. For example, the account management system 160 does not receive any new user 101 account identifiers along with the same merchant beacon identifier code within a threshold length of time and determines that no new users 101 have entered the network 170 range of the merchant beacon device 120.

In block 930, the account management system 160 determines whether a current user 101 has moved out of range of the merchant beacon device 120. In an example embodiment, the user computing device 110 continues to receive from the merchant beacon identifier code from the merchant beacon device 120 and retransmit the merchant beacon identifier code along with the user 101 account identifier to the account management system 160. In this example embodiment, the user computing device 110 may periodically transmit information comprising the merchant beacon identifier code and user 101 account identifier to the account management system 160 as long as the user computing device 110 continues to detect the merchant beacon device 120 and receive the merchant beacon device 120 identifier via periodic scans. For example, the user computing device scans for the merchant beacon device 120 every five seconds. In another example embodiment, the user computing device 110 may periodically transmit information comprising the merchant beacon identifier code and user 101 account identifier to the account management system 160 as long as the user computing device 110 maintains a wireless network 170 connection with the merchant beacon device 120. For example, the user computing device 110 may transmit this information to the account management system 160 at every five seconds. In this example embodiment, if the account management system 160 ceases to receive the information from the user computing device for a predefined number of intervals, the account management system 160 may determine that the corresponding user 101 has moved out of range of the merchant beacon device. In this example embodiment, if the account management system 160 continues to receive the information transmitted by the user computing device 110 at the expected intervals, the account management system 160 determines that the user 101 is still in network 170 range of the merchant beacon device 120.

If no current user 101 has moved out of range of the merchant beacon device 120, the method 860 proceeds to block 250 in FIG. 2. For example, the account management system 160 continues to receive the merchant beacon identifier code and user 101 account identifier transmitted by the user computing device 110 at the expected intervals and determines that the user 101 is still in network 170 range of the merchant beacon device 120.

Returning to FIG. 9, in block 930, if a current user 101 has moved out of range of the merchant beacon device 120, the method 860 proceeds to block 940.

In block 940, the merchant camera device 140 receives a notification from the account management system 160 that a current user 101 is out of network range of the merchant beacon device 120. In another example embodiment, the merchant camera device 140 receives a notification from the account management system 160 that the user computing device 110 associated with the current user 101 has stopped sending notifications to the account management system 160 comprising the merchant beacon device 120 identifier. For example, the merchant camera device 140 receives the user 101 account identifier associated with the current user 101 associated with a user computing device 110 that is either out of network range or has stopped transmitting notifications comprising the merchant beacon device 120 identifier to the account management system 160. In yet another example embodiment, the merchant point of sale device 130 receives the notification from the account management system 160 that the current user 101 is out of network range of the merchant beacon device 120. The merchant camera device 140 accesses the current customer log and finds an entry corresponding to the current user 101 that is out of network range of the merchant beacon device 120. For example, the current customer log is maintained by the account management system 160 and the merchant camera device 140 accesses the current customer log over the network 170 by communicating with the account management system 160. In another example embodiment, the account management system 160 does not transmit a notification to the merchant camera device 140 that the current user 101 is out of network range. In this example embodiment, the account management system 160 accesses the current customer log and deletes the facial template of the current user 101 from the current customer log.

In block 950, the merchant camera device 140 deletes the facial template of the current user 101 from the current customer log. For example, the current customer log comprises a table and the merchant camera device 140 deletes or requests the deletion of an entry or row corresponding to data associated with the current user 101 for which the merchant camera device 140 received the notification. In another example embodiment, the account management system 160 accesses the current customer log and deletes the facial template of the current user 101 from the current customer log.

From block 950, the method 860 proceeds to block 250, in FIG. 2.

Returning to FIG. 2, in block 250, the user 101 initiates a transaction at the merchant point of sale device 130. The method for initiating, by a user 101, a transaction at a merchant point of sale device 130 is described in more detail hereinafter with reference to the method 250 described in FIG. 10. In the example embodiments described herein, the user 101 initiates a “hands free transaction” at the merchant POS device 130. An example hands free transaction does not require any interaction with the user computing device 110 on the part of the user 101. In another example, a hands free transaction requires only minimal interaction with the user computing device 110 by the user 101.

FIG. 10 is a block diagram depicting a method 250 for initiating, by a user 101, a transaction for a restricted product or service at a merchant point of sale device 130, in accordance with certain example embodiments. The method 250 is described with reference to the components illustrated in FIG. 1. In other example embodiments, the user 101 requests a service at a computing device associated with a service provider system (not depicted). For example, a service may comprise accessing a restricted area or accessing restricted information via the computing device associated with the service provider system. In these other example embodiments, the method for requesting a service at the computing device associated with the service provider system may be similar to the method 250 for initiating by the user 101, a transaction for a restricted product or service at the merchant point of sale device.

In block 1010, the user 101 approaches the merchant point of sale device 130. In an example embodiment, at a time prior to approaching the merchant POS device 130, the user 101 browses the merchant system location and selects one or more items to purchase. In this example embodiment, the user 101 may collect the one or more items and carry, or otherwise transport via physical basket or shopping cart, the one or more items to the merchant POS device 130. In another example embodiment, the merchant system location comprises a restaurant or other location at which the user 101 remains seated and a merchant point of sale device 130 operator carries a portable merchant point of sale device 130 to the user's 101 area.

In block 1020, the merchant point of sale device 130 operator 102 totals the items of the user 101 for purchase. In an example embodiment, the merchant POS device operator 102 scans barcodes attached to the one or more items or otherwise enters descriptions and prices associated with the one or more items into the merchant POS device 130. In an example embodiment, after scanning or manually entering the items into the merchant POS device 130, the merchant POS device operator 102 actuates an object on the user interface 135 of the merchant POS device 130 to order the merchant POS device 130 to total the items. In an example embodiment, the merchant POS device 130 displays, via the user interface 135, the total to the user 101. In the example embodiments described herein, at least one of the products or services being purchased by the user 101 comprises a restricted product or service. For example, certain products, such as alcohol, may be age-restricted purchases only allowed by customers at or over the age of 21. Other products or services provided at the merchant system location may be restricted to users associated with other criteria in addition to or instead of age. In another example, certain products or services may only be purchased by users 101 that are enrolled in a rewards program or are members of a club. In an example, a restricted service may comprise a discount on a purchase. For example, certain discounts may be restricted to users 101 above a certain age. For example, the merchant system location may offer a senior-citizen discount.

In block 1030, the merchant point of sale device 130 operator asks the user 101 to select a payment option. In an example embodiment, the merchant POS device 130 displays one or more payment options that the user 101 may select to use in a transaction. Example payment options may comprise payment via an application 113 associated with the account management system 160, payment by cash, payment by check, payment by credit card, payment by debit card, and/or any other means of payment that the merchant system can or is willing to accept for payment from the user 101. In an example embodiment, the one or more payment options are displayed as objects on the user interface 135 and are selectable by the merchant POS device operator 102 in response to the user 101 directing the merchant POS device 102 operator to make a selection.

In another example embodiment, the account management system 160 or merchant camera device 140 transmits a notification to the merchant point of sale device 140 that the user 101 is able to initiate a transaction via the application 113. In this example embodiment, the merchant point of sale device 140 notifies the merchant point of sale device 140 operator that the user 101 is able to participate in transaction using the application 113. In this example embodiment, the merchant point of sale device 140 operator asks the user 101 to confirm whether the user 101 wants to initiate a transaction using the application 113.

In block 1040, the user 101 directs the merchant point of sale device operator 102 to initiate a transaction via the application 113. In an example embodiment, in response to receiving a verbal request from the user 101 to select the application 113 as a payment option, the merchant POS device operator 102 actuates an object on the user interface 135 of the merchant POS device 130 corresponding to the application 113 payment option.

In block 1050, the merchant point of sale device operator 102 selects an option on the merchant point of sale device 130 to initiate a transaction comprising one or more restricted products or services using the application 113. In an example embodiment, the merchant POS device 130 displays a confirmation screen after the merchant POS device operator 102 selects an option to initiate a transaction using the application 113. An example confirmation screen may display information summarizing the potential transaction and comprising one or more of a transaction total, a description of the one or more items being purchased by the user 101, and an indication that the user 101 selected the application 113 as the method of payment for the transaction. An example confirmation screen may indicate to the merchant system POS device operator and/or the user 101 the transaction comprises a purchase of one or more restricted products or services and may include further information describing eligibility requirements for purchasing the restricted one or more products or services. An example confirmation screen may further display options to confirm the transaction or cancel the transaction. In an example embodiment, the user 101 reviews the confirmation screen, determines that the information displayed on the confirmation screen is correct, determines to continue with the transaction, and directs the merchant POS device operator 102 to select the option to confirm the transaction via the user interface 135.

In another example embodiment, the user 101 decides to abandon the transaction because the information is incorrect or because the user 101 changed his mind and decided not to purchase the items. In another example embodiment, the user 101 decides to abandon the transaction because the user 101 does not believe he meets the eligibility requirements to purchase one or more of the one or more restricted products or services. In yet another example embodiment, the confirmation screen further comprises an option to edit the transaction details. In this example embodiment, the merchant POS device operator 102, upon direction of the user 101, may select the option to edit the transaction details and may then edit, add, or delete one or more of the items in the transaction or edit payment details or payment methods for the transaction.

In block 1060, the merchant point of sale device 130 transmits a request to identify the user 101 to the account management system 160. In an example embodiment, the merchant point of sale device transmits a request to process a transaction along with the request to identify the user 101.

For example, at this point, the account management system 160 is aware that one or more users 101 are physically present in the merchant system location based on the current customer log maintained by the account management system and accessible and editable by the merchant camera device 120. Additionally, the account management system 160 is aware that a user 101 has initiated a transaction with the application 113 payment method based on the request to process the transaction received from the merchant POS device 130. However, the account management system 160 may not be aware of exactly which user 101 requested to process the hands free transaction involving the application 113.

In block 1070, the account management system 160 receives the request to identify the user 101 from the merchant point of sale device 130. For example, the account management system 160 receives the request to identify the user and the request to process the transaction over the network 170.

In block 1080, the account management system 160 transmits a request to the merchant camera device 140 to identify the user 101. For example, the account management system 160 transmits the request to identify the user to the merchant camera device 140 over the network 170. In another example embodiment, the merchant camera device 140 has already communicated the identity of the user 101 to the account management system 160 or to the merchant point of sale device 130 and the account management system 160 does not need to transmit a request to the merchant camera device 140 to identify the user 101.

From block 1080, the method 250 proceeds to block 260 in FIG. 2.

Returning to FIG. 2, in block 260, the merchant camera device 140 identifies the user 101 via facial recognition. The method for identifying, by a merchant camera device 140, a user 101 via facial recognition is described in more detail hereinafter with reference to the method 260 described in FIG. 11. In other example embodiments, In other example embodiments,

FIG. 11 is a block diagram depicting a method 260 for identifying, by a merchant camera device 140, a user 101 via facial recognition, in accordance with certain example embodiments. The method 260 is described with reference to the components illustrated in FIG. 1. In other example embodiments, a camera device associated with a service provider system and installed at a location of the service provider system identifies the user 101 via facial recognition. In these other example embodiments, the method for identifying, via the camera device, the user via facial recognition may be similar to the method 260 for identifying, by a merchant camera device 140, a user 101 via facial recognition.

In block 1110, the merchant camera device 140 captures photo images and/or video of the user 101. In an example embodiment, in response to receiving a request to identify the user 101, the merchant camera device 140 activates the camera 147 to begin to capture photo images and/or a video of the surroundings of the merchant camera device 140. In an example embodiment, the merchant POS device 130 captures a video feed of the user's 101 face. In another example embodiment, the merchant camera device 140 continuously captures, but does not record, a video feed of its surroundings. In this example embodiment, when the merchant camera device 140 receives a request to identify the user 101 from the account management system 160, the merchant camera device brings to record the video feed for a threshold amount of time. In an example embodiment, the user 101 may be moving during the period in which the merchant camera device 140 records the video feed. In an example embodiment, a processor 143 of the merchant camera device 140 extracts a facial image by determining a particular frame of the video feed and area of the instance of the video feed corresponding to the face of the user.

In block 1120, the merchant camera device 140 extracts a facial image of the user 101 from the captured video. In an example embodiment, the merchant camera device 140 determines a frame of the captured video to provide an image of the user's 101 face and extracts the frame of the captured video comprising the facial image of the user 101.

In certain other example embodiments, the merchant camera device 140 determines a frame of the captured video to provide an image of the faces of a plurality of users 101. For example, the frame comprises an image of the face of a first user 101, a second user 101, and a third user 101 at different locations in the image. In this example, one merchant camera device 140 may capture video of an environment corresponding to an area in the proximity of multiple merchant POS devices 130. In this example embodiment, the merchant camera device 140 may determine to which particular merchant POS device 130 each of the plurality of faces of the corresponding plurality of users 101 in the extracted image.

In an example embodiment, in which a merchant camera device 140 is mounted at an angle parallel to a plurality of adjacent merchant POS devices 130, the field of view of the merchant camera device 140 may be divided into bounding boxes such that each bounding box is assigned to a particular merchant POS device 130. In this example embodiment, since one or more users 101 may be situated between any two adjacent merchant POS devices 130, the bounding boxes may overlap. In this example embodiment, each bounding box is assigned to at most two adjacent merchant POS devices 130. In this example embodiment, in which the merchant camera device 140 is mounted parallel to a plurality of adjacent merchant POS devices 130, the size of a detected facial image of a user 101 is directly proportional to the distance the user 101 is from a merchant POS device 130 detected in the image. In this example embodiment, the merchant camera device 140 assigns each detected facial image to one or two particular merchant POS devices 130 based on the position of the facial image relative to the bounding boxes.

In another example embodiment, the merchant camera device 140 is mounted at an angle that is not parallel to a plurality of adjacent merchant POS devices 130. In this example embodiment, the merchant camera device 140 may be able to monitor an environment comprising a greater number of adjacent merchant POS devices 130 than the example embodiment in which the merchant camera device 140 is mounted parallel to adjacent merchant POS devices 130. In this example embodiment, however, the size of a detected facial image is not proportional to the distance between a merchant POS terminal detected in the image and the detected facial image. In this example embodiment, the merchant camera device 140 assigns each detected facial image to one or two particular merchant POS devices 130 based on the position of the facial image relative to the bounding boxes.

In block 1130, the merchant camera device 140 generates a facial template from the captured facial image. In an example, the facial template is of a predetermined size, for example, a 128-byte facial template. In an example, the account management system 160 generates a facial template comprising a computer code representation of the digital facial image. For example, the facial template may describe key features of the facial image of the user 101, such as shape, color, line, value, space, form, texture, or other useful or relevant feature of the image or of particular regions of the image. In another example, the facial template is generated by processing the facial image through a convolutional neural network. In an example embodiment, the merchant camera device 140 stores the generated facial template in a data storage unit 146 associated with the merchant camera device 140. For example, the merchant camera device 140 database may comprise a log of facial templates of current customers wherein the merchant camera device 140 stores the generated facial template.

In certain other example embodiments, the merchant camera device 140 continuously captures a video feed of its surroundings as users 101 enter and leave the vicinity of one or more merchant POS devices 130 over the course of a certain time period. In this example embodiment, the merchant camera device 140 processor 147 is able to continuously monitor the incoming video feed to detect faces from extracted frames of the video feed. In this example embodiment, the merchant camera device 140, each time the processor 147 detects the presence of one or more faces in the video feed, the merchant camera device 140 extracts a frame of the video feed comprising one or more facial images of one or more corresponding detected faces and creates facial templates based on the extracted one or more facial images.

In this example embodiment, the merchant camera device 140 stores facial templates in the log of facial templates of current customers as they are generated. As the merchant camera device 140 generates a subsequent facial template, the merchant camera device 140 determines whether the generated subsequent facial template is similar to any of the facial templates stored in the log of facial templates of current customers. If the generated subsequent facial template is within a comparison threshold to any of the facial templates already stored in the log, the merchant camera device 140 associates the subsequent facial template to one or two particular merchant POS devices 130 based on the position of the associated facial images in the extracted frame of the captured video and adds the facial template to the log of facial templates of current customers.

If the subsequent facial template is not similar to any facial templates already stored in the log of facial templates of current customers, the merchant camera device 140 deletes, ignores, or does nothing with the subsequent facial template. In this example embodiment, if the merchant camera device 140 determines that a certain facial image is no longer in the field of the video feed, the corresponding facial template is deleted from the log of facial templates of current customers.

In block 1140, the merchant camera device 140 deletes the captured video and the extracted facial image. For example, the merchant camera device 140 does not store captured images or video. In this example, facial templates generated by the merchant camera device 140 comprise computer code representations of facial images of users 101. In this example, after generating a facial template or after a threshold time has passed after capturing video or images or extracting an image from a video, the merchant camera device 140 deletes any captured or extracted video or images.

In block 1150, the merchant camera device 140 retrieves facial templates from the current customer log. For example, the current customer log comprises facial templates received from the account management system 160 corresponding to all current users 101 whose associated user computing devices 110 are located within a network distance of a merchant beacon device 120.

In block 1160, the merchant camera device 140 compares the generated facial template from the captured facial image to facial templates from the current customer log. In another example embodiment, the account management system 160 compares the generated facial template from captured facial image to facial templates from the current customer log. Comparing the generated facial template generated from the captured facial image to facial templates from the current customer log may comprise comparing one or more individual features or components of the templates. For example, the facial template may describe key features of the facial image of the user 101, such as shape, color, line, value, space, form, texture, or other useful or relevant feature of the image or of particular regions of the image.

In an example, a match comprises a complete match between the generated facial template and a facial template from the current customer log. In another example, a match comprises a similarity greater than a predefined threshold similarity between the generated facial template and a facial template from the current customer log. For example, the merchant camera device 140 determines a similarity value for each of the one or more individual features or components between the generated facial template and the facial template from the current customer log. In this example, the merchant camera device 140 may then determine an overall similarity value between the generated facial template and the facial template from the current customer log and compare the overall similarity value against the predefined threshold similarity value. If the overall similarity value is greater than or equal to the predefined threshold similarity value, the merchant camera device 140 may determine that there is a match between the generated facial template and the facial template from the current customer log. However, if the overall similarity value is less than the predefined threshold similarity value, the merchant camera device 140 may determine that there is no match between the generated facial template and the facial template from the current customer log.

In block 1170, the merchant camera device 140 determines whether there is a match between the generated facial template and one of the facial templates from the current customer log. In this example embodiment, when the merchant camera device 140 determines a match between a first facial template in the log of facial templates of current customers and a second facial template the log of current customers, the merchant camera device 140 determines the identity of the merchant one or two POS devices 130 that the second facial template is associated with. In this example embodiment, the merchant camera device 140 updates the entry of the second facial template in the log of current customers with an annotation assigning the second facial template to a particular one or two merchant POS devices 130. For example, as previously discussed, the facial image upon which the facial template was based was determined to be located within a bounding box of an area of the video or image corresponding to one or two merchant POS devices 130. In this example, when the merchant camera device 140 generates a facial template for the facial image, the merchant camera device 140 associates the generated facial template with the particular one or two merchant POS devices 130. For example, if the facial image was in a bounding box in front of a first merchant POS device 130, the resulting facial template may be associated with the first merchant POS device 130. In another example, if the facial image was in a bounding box between the first merchant POS device 130 and a second, adjacent POS device 130, the resulting facial template may be associated with both the first merchant POS device 130 and the second merchant POS device 130.

If a facial template from the current customer log matches the generated facial template, the method 260 proceeds to block 1180. In another example embodiment, if a facial template from the current customer log matches a facial template from the log of facial templates of current customers, the method 260 proceeds to block 1180

In block 1180, the merchant camera device 140 transmits the facial template from the current customer log, which corresponds to the identified user, to the account management system 160. For example, the transmitted facial template comprises an annotation assigning the facial template to a particular one or two merchant POS devices 130.

From block 1180, the method 260 proceeds to block 290 in FIG. 2. In this example embodiment, the account management system 160 identifies the user 101 requesting the transaction and the particular merchant POS device 130 to which the user 101 is assigned and/or may be proceeding with the processing the transaction.

Returning to block 1170, if none of the facial templates from the current customer log matches the generated facial template, the method 260 proceeds to block 270 in FIG. 2. In another example embodiment, if none of the facial templates from the current customer log matches any of the facial templates from the log of facial templates of current customers, the method 260 proceeds to block 270 in FIG. 2.

Returning to block 270, in FIG. 2, the account management system 160 identifies the user 101 via voice recognition. In an example embodiment, none of the facial templates from the current customer log matches the generated facial template. In another example embodiment, the account management system 160 does not identify the user 101 via voice recognition and proceeds to identify the user 101 via challenge and response. For example, the merchant camera device 140 and/or account management system 160 is unable to identify the user via facial recognition. The method for identifying, by an account management system 160, a user 101 via voice recognition is described in more detail hereinafter with reference to the method 270 described in FIG. 12.

FIG. 12 is a block diagram depicting a method 270 for identifying, by an account management system 160, a user 101 via voice recognition, in accordance with certain example embodiments. The method 270 is described with reference to the components illustrated in FIG. 1.

In certain example embodiments, it may be necessary to identify a user 101 via voice recognition because the merchant camera device 140 and/or account management system 160 is not able to identify the user 101 based on facial recognition. For example, the merchant camera device 140 may be unable to extract an adequate facial image of the user 101 from the video feed to generate a facial template. In another example, the merchant camera device 140 is unable to find a match for the facial template of the user 101 in the current customer log. In yet another example, the merchant camera device 140 identifies a matching user 101 facial template in the current customer log, however, the identified user 101 facial template is assigned to two adjacent merchant POS devices 130. In this example, the user 101 may have to identify himself via voice recognition at the POS device 130 at which the user 101 initiates the transaction.

In block 1210, the merchant camera device 140 transmits a notice that the user 101 cannot be identified to the account management system 160. In another example embodiment, the merchant camera device 140 transmits a notice that the user 101 has been identified, however, that the merchant camera device 140 is unable to determine which of two adjacent merchant POS devices 130 the user 101 using in the transaction.

In block 1220, the account management system 160 retrieves audio templates corresponding to users 101 from the current customer log. As previously discussed, when a user 101 establishes an account with the account management system 160, the user 101 may submit an audio recording of the user's 101 voice to the account management system 160. In this example the account management system 160 establishes an audio template corresponding to the user 101 based on the received audio recording. In another example embodiments, the user 101 does not submit an audio recording to the account management system 160 at the time the user 101 establishes the user 101 account. In this other example embodiment, the account management system 160 does not have an audio template associated with the user 101 account and cannot verify the user 101 via voice recognition.

In block 1230, the account management system 160 transmits a request to the merchant system point of sale device 130 to record audio of the user 101. For example, the account management system 160 transmits the request over the network 170.

In block 1240, the merchant system point of sale device 130 displays the request for the user 101 to record audio. For example, the merchant system POS device 130 may display directions to the user 101 to record an audio recording. For example, the user 101 may be directed to speak the same words in the same intonation as the user 101 did when establishing the audio template with the account management system 160 at the time of setting up the user 101 account.

In block 1250, the merchant system point of sale device 130 records a voice input of the user 101 and transmits the voice input to the account management system 160. For example, the merchant POS device operator 102 may actuate an object on the user interface 135 to activate an audio component 131 to receive an audio input of the user 101. The merchant system POS device 130 records the audio input and transmits the audio input to the account management system 160 over the network 170. In an example embodiment, the merchant POS device 130 transmits a merchant POS device 130 identifier along with the retransmitted user 101 audio input.

In block 1260, the account management system 160 compares the received voice input against the retrieved audio templates corresponding to users 101 from the current customer log. For example, the account management system 160 receives the audio input of the user 101 from the merchant POS device 130 over the network 170. Comparing the generated audio template generated from the captured user 101 audio to audio templates from the current customer log may comprise comparing one or more individual features or components of the templates. For example, the audio template may describe key features of the audio of the user 101, such as pitch or volume. In an example, a match comprises a complete match between the generated audio template and an audio template from the current customer log. In another example, a match comprises a similarity greater than a predefined threshold similarity between the generated audio template and an audio template from the current customer log.

In block 1270, the account management system 160 determines whether there is a match between the received voice input and one of the retrieved audio templates from the current customer log. In an example embodiment, the account management system 160 compares one or more features between the received voice input and each of the retrieved audio templates from the current customer log. In an example embodiment, if the similarity between the received voice input and a particular audio template exceeds a predefined threshold, the account management system 160 determines that the received voice input matches the particular audio template. In another example embodiment, if the similarity between the received voice input and the particular audio template is less than the predefined threshold, the account management system 160 determines that the received voice input does not match the particular audio template.

If an audio template from the current customer log matches the received voice input, the method 260 proceeds to block 1280. For example, the similarity between a particular audio template from the current customer log and the received audio recording of the user 101 exceeds a predefined threshold and the account management system 160 determines that there is a match.

In block 1280, the account management system 160 assigns the user 101 to the merchant point of sale device 130 identified in the current customer log. For example, the account management system 160 identifies the user 101 associated with the audio template that matches the received user 101 audio recording. Additionally, the account management system 160 identifies the merchant POS device 130 to which the user 101 should be assigned based on the merchant POS device 130 identifier received from the merchant POS device 130 with the user 101 audio recording.

From block 1280, the method 270 proceeds to block 290 in FIG. 2. For example, the account management system 160 successfully identified the user 101 based on comparing the received user 101 recording against audio templates from the current customer log. In this example, the account management system 160 may continue to process the transaction involving the identified user 101.

Returning to block 1270, if none of the audio templates from the current customer log matches the received voice input, the method 270 proceeds to block 280 in FIG. 2. In another example embodiment, the merchant POS device 130 is unable to receive an audio recording of the user 101 or the received audio recording of the user 101 is inadequate or cannot be used to identify the user 101.

Returning to FIG. 2, in block 280, the user 101 is identified by the merchant system POS device operator 102 via a challenge and a response. The method for identifying, by a merchant point of sale device operator 102, a user 101 via a challenge and a response is described in more detail hereinafter with reference to the method 280 described in FIG. 13.

FIG. 13 is a block diagram depicting a method 280 for identifying, by a merchant point of sale device operator 102, a user 101 via a challenge and a response, in accordance with certain example embodiments. The method 280 is described with reference to the components illustrated in FIG. 1. In other example embodiments, a service provider system computing device operator identifies the user 101 via a challenge and response. In an example embodiment, the method for identifying the user by the service provider computing device operator via a challenge and a response may be similar to the method 280 for identifying, by a merchant point of sale device operator 102, a user 101 via a challenge and a response.

In block 1310, the point of sale device operator 102 issues a challenge to the user 101. In an example embodiment, the point of sale device operator 102 issues the challenge to the user 101 only when the user 101 could not be identified via facial or voice recognition. In another example embodiment, the point of sale device operator 102 issues the challenge to the user 101 as an additional security measure even if the user 101 has already been identified via facial or voice recognition. In an example, the merchant POS device operator 102 asks the user 101 for the initials of the user 101. In another example, the merchant POS device operator 102 asks the user 101 for the last four digits of the phone number of the user 101. In another example, the merchant POS device operator 102 asks the user 101 for a configured password. Any suitable challenge may be issued by the merchant POS device operator 102. In an example embodiment, the response to the challenge does not provide any secure or private information.

In block 1320, the user 101 provides a challenge response. As described in the example challenges, the responses may be the initials of the user 101, the last four digits of the phone number of the user 101, or a configured password. Any configured challenge response may be utilized. In certain embodiments, the response may be a spoken response, a hand gesture, a keypad entry, a display of an identification card, or any suitable response.

In block 1330, the point of sale device operator 102 inputs the response into the merchant point of sale device 130. The merchant POS device operator 102 inputs the challenge response of the user 101. In an example, if the user 101 indicates that the initials of the user 101 are “AC,” then the merchant POS device operator 102 inputs “AC” into the application 133 of the merchant POS device 130. In an example, the user interface 135 of the merchant POS device 130 displays a request for an entry of the response of the user 101. The merchant POS device operator 102 enters the response via a virtual or physical keyboard, voice dictation, or in any suitable manner. In an alternate example, the user 101 enters the response into the user interface 135 of the merchant POS device 130.

In block 1340, the merchant point of sale device 130 displays potential users 101 based on the challenge response. The merchant POS device 130 displays potential users 101 based on the challenge response. A list of users 101 that are associated with the challenge response are displayed on the merchant POS device 130 to the merchant POS device operator 102. For example, if ten customers are in the vicinity of the merchant beacon device 120, then the merchant POS device 130 may have received from the account management system 160 a challenge response associated with each of the respective ten customers. When the merchant POS device 130 receives the challenge response input, only the potential users 101 that are associated with the challenge response are displayed to the merchant POS device operator 102.

In another embodiment, the merchant POS device 130 or the account management system 160 which processes the challenge, presents additional challenges until there is a single matching user 101 remaining.

In the example, if the merchant POS device operator 102 inputs “AC” as the initials of the user 101 associated with the transaction, then only the potential users 101 with those initials will be displayed to the merchant POS device operator 102 by the application 133. The application 133 accesses a database on the account management system 160 or another computing device and identifies the initials of the potential users 101 that have provided tokens. The application 133 identifies the one or more potential users 101 that have the initials “AC” and displays the identified user 101 accounts to the merchant POS device operator 102. In the example, two of the ten customers that are in the vicinity of the merchant beacon device 120 have the initials “AC.” The user 101 accounts of the two customers are displayed to the merchant POS device operator 102.

In certain example embodiments, all of the nearby customers who have had tokens transmitted to the merchant POS device 130 are presented to the merchant POS device operator 102 and the merchant POS device operator 102 selects the appropriate user 101 account.

The application 133 may display a picture of the potential user 101 accounts that are presented to the merchant POS device operator 102. For example, each user 101 may associate a picture with a user 101 account. When the merchant POS device 130 presents the one or more potential user 101 accounts to the merchant POS device operator 102, the merchant POS device operator 102 may select the appropriate user 101 account based on the picture matching the user 101 conducting the transaction. Other identifying information may be presented instead of, or in addition to, a picture. For example, the name of the user 101 may be displayed and the merchant POS device operator 102 may identify the potential user 101 with that name. Any other suitable identifying information may be presented.

In block 1350, the merchant point of sale device operator 102 selects the user 101 account for use in a transaction. After identifying the displayed picture of the user 101, the merchant POS device operator 102 may input a selection of the user 101 by actuating a user interface 135 control associated with the picture, or by inputting the selection in any suitable manner. If the picture doesn't match any of the potential users, then the merchant POS device operator 102 may cancel the transaction, notify the user 101 of the discrepancy, or perform any other suitable action.

In an example, only a single user 101 account is presented in the list of potential users 101. If only a single user 101 account is identified, then the method may proceed after the merchant POS device operator 102 verifies that the displayed picture matches the user 101. If the picture doesn't match, then the merchant POS device operator 102 may cancel the transaction, notify the user 101 of the discrepancy, or perform any other suitable action.

From block 1350, the method 280 proceeds to block 290 in FIG. 2.

Returning to FIG. 2, in block 290, a transaction is processed. The method for processing a transaction is described in more detail hereinafter with reference to the method 290 described in FIG. 14.

In another example embodiment, instead of processing a transaction, a computing device associated with a service provider system provides a service to the user 101. The method for providing, by the computing device associated with the service provider system may be similar to the method 290 of processing a transaction.

FIG. 14 is a block diagram depicting a method 290 for processing a transaction, in accordance with certain example embodiments. The method 290 is described with reference to the components illustrated in FIG. 1.

In block 1410, the account management system 160 transmits account information of the identified user 101 to the merchant point of sale device 130. For example, the user 101 account with the account management system 160 comprises payment account information associated with one or more payment accounts of the user 101. An example payment account of the user 101 comprises a credit account, bank account, stored value account, gift card, merchant system charge account, or other relevant user 101 account. In an example embodiment, the merchant POS device 130 does not receive complete payment information for one or more of the user 101 payment accounts. For example, the payment information may be obfuscated or truncated. For example, the merchant POS device 130 may only receive abbreviated payment information sufficient for a user 101 to identify a payment account via the user interface 135. In an example embodiment, account information of the user further indicates whether the user is eligible to purchase or receive one or more restricted products or service. In another example embodiment, the account information of the user further comprises demographic data, a record of membership in rewards programs or clubs, or other data associated with the user that may be relevant determining, by an operator of the merchant POS device 130, that the user is eligible or ineligible to purchase or receive a restricted product or service.

In block 1415, the merchant POS device 130 operator determines whether the user 101 is eligible for the transaction based on the user 101 account information. In an example embodiment, the merchant point of sale device displays account information of the user to the merchant point of sale device operator and the merchant point of sale device operator decides whether the user is eligible for a service based on the user's account information and the merchant POS device 130 operator's knowledge of policies and rules of the merchant system and/or legal jurisdictions where the merchant system location is located.

In another example embodiment, the merchant POS device 130 automatically determines whether the user 101 is eligible for the transaction based on the user 101 account data. For example, the merchant POS device 130 comprises stored data indicating merchant system requirements and/or legal requirements for purchasing all possible restricted products or services provided at the merchant system location. The merchant POS device 130 determines whether the user 101 is eligible for the restricted service or product by finding data in the user 101 account information matching the requirements listed in the stored data for purchasing the product or service. For example, if the legal requirement to purchase the product is 21 or older, and the user 101 age listed in the account information is 22, the merchant POS device 130 determines that the user 101 is eligible to purchase the product based on determining, based on information stored in the merchant POS device 130, that the requirement to purchase a restricted product is an age of 21 years old or older and then determining that the user's 101 age being greater than or equal to 21 based on the user 101 account information.

If the merchant POS device 130 operator or merchant POS device 130 determine that the user is not eligible for the restricted transaction, the method 290 proceeds to block 1420. For example, the legal requirement to purchase a product in the desired transaction is 21 or older, and the user's 101 age listed in the account information and displayed to the merchant POS device 130 operator 102 via the merchant POS device 130 is 17. Based on the merchant POS device 130 operator's knowledge of the legal age requirement to purchase the product, the merchant POS device 130 operator denies processing the transaction to purchase the product and denies providing the product to the user 101.

In another example, the merchant POS device 130 automatically determines that the user 101 is not eligible for the transaction based on the user 101 account data. For example, the merchant POS device 130 comprises stored data indicating that the requirement to purchase the restricted product is an age of 21 years or older and the merchant POS device 130 determines that the user 101 is not eligible for the restricted product by finding data in the user 101 account information indicating that the user 101 is 17 years old and determining that 17 is less than the age requirement of greater than or equal to 21.

In another example embodiment, instead of determining ineligibility of the user 101 to purchase or receive the restricted product or service, the merchant POS device 130 operator or merchant POS device 130 determine that the data in the user 101 account information disqualifies the user 101 from using a discount or offer. For example, a merchant system policy to apply a “senior discount” to a transaction is that a user 101 must be 65 years or older, and the user 101 age listed in the account information and displayed to the merchant POS device 130 operator via the merchant POS device 130 is 55. Based on the merchant POS device 130 operator's knowledge of the merchant system age requirement to apply the senior discount to a transaction, the merchant POS device 130 operator will not apply the senior discount to the requested transaction.

In another example, the merchant POS device 130 automatically determines that the user 101 is not eligible for the restricted discount based on the user 101 account data. For example, the merchant POS device 130 comprises stored data indicating that the requirement to apply the restricted discount is an age of 65 years or older and the merchant POS device 130 determines that the user 101 is not eligible for the restricted product by finding data in the user 101 account information indicating that the user 101 is 55 years old and determining that 55 is less than the age requirement of greater than or equal to 65. In an example embodiment, the merchant point of sale device 130, in response to determining that the user 101 is not eligible for a restricted transaction or restricted discount displays information via the user interface of the merchant POS device 130 informing the merchant POS device 130 operator that the user 101 ineligible for the respective restricted product, service, or discount. In this example embodiment, the merchant point of sale device 130 operator may take appropriate action based on the displayed information, such as informing the user of ineligibility to purchase a restricted product or service or to apply a discount and/or not applying the discount. In certain example embodiments, when the user 101 is ineligible for the restricted discount, the merchant POS device 130 operator does not need to inform the user, but may just continue with the current transaction without applying the restricted discount.

In block 1420, the merchant point of sale device 130 operator informs the user 101 that the user 101 is ineligible for the restricted transaction. In another example embodiment, when a restricted discount is being considered, the merchant point of sale device 130 operator continues with the transaction (if there are no restricted products for which the user 101 is ineligible) but does not apply the restricted discount. In other example embodiments, in which the user 101 desires a restricted service at a service provider system location, the operator of the computing device at the service provider location informs the user 101 that the user 101 is ineligible for the restricted service. For example, the computing device operator informs the user that the user may not access a restricted area or access restricted information. In an example embodiment, the merchant POS device 130 operator may select one or more user interface objects on the merchant POS device 130 to cancel the current transaction based on determining the user's ineligibility for the transaction. In another example embodiment, the merchant POS device 130 operator may cancel a particular restricted item or service from the transaction by selecting one or more interface objects on the merchant POS device 130 based on determining the user's 101 ineligibility to purchase the particular restricted product in the transaction.

Returning to block 1415, in FIG. 14, if the merchant POS device 130 operator determines that the user 101 is eligible for the purchase of the restricted product/service or the application of the restricted discount or offer, the method 290 proceeds to block 1430.

In block 1430, the merchant POS device 130 operator selects an option to continue with the restricted transaction. For example, the merchant POS device 130 operator, based on the user's 101 eligibility for the transaction comprising the restricted product or service, selects one or more interface objects on the merchant POS device 130 to continue processing the transaction for the restricted product or service. In another example, the merchant POS device 130 operator, based on the user's 101 eligibility for a restricted discount or offer, selects one or more interface objects on the merchant POS device 130 to apply the restricted discount or offer to the current transaction and to continue processing the current transaction.

In certain example embodiments described herein, in response to the merchant POS device 130 operator selecting an option to continue with a restricted transaction or in response to the merchant POS device 130 operator selecting an option to apply a restricted discount and to continue processing the current transaction, the merchant POS device 130, the merchant POS device 130 operator, and the account management system 160 process a transaction as described in blocks 1440-1490 in FIG. 14. In certain other example embodiments described herein, in response to the merchant point of sale device 130 automatically continuing with a transaction for a restricted product or service or automatically applying a restricted discount or offer based on determining the user's 101 eligibility for the restricted product, service, discount or offer, the merchant POS device 130, the merchant POS device 130 operator, and the account management system 160 proceed to process a transaction as described in blocks 1440-1490 in FIG. 14. However, in certain other example embodiments, instead of processing a transaction as described in blocks 1440-1490 in FIG. 14, a computing device associated with a service provider system provides a service to the user 101 based on determining the user's 101 eligibility for the service.

In block 1440, the merchant point of sale device 130 displays accounts of the identified user 101. In an example embodiment, the merchant POS device 130 does not display complete account information of the user 101 on the user interface 135. For example, for a credit card account, the merchant POS device user interface 135 may display only the name associated with the credit card, last four digits of the credit card number, and the expiration date.

In block 1450, the merchant point of sale device operator 102 selects a user 101 account for transaction and confirms the transaction with permission of the user 101. For example, the user 101 views the account options directly displayed on the user interface 135 or listens to the merchant POS device operator 102 read the user 101 payment account options to the user 101. In an example embodiment, the user 101 selects a payment account option to use in the transaction. For example, the user 101 decides to use a credit card account. In an example embodiment, the user 101 communicates a selection of a payment account for use in the transaction to the merchant POS device operator 102. In an example embodiment, in response to receiving the user's 101 indication of the payment account, the merchant POS device operator 102 selects the payment account indicated by the user 101 on the merchant POS device user interface 135.

In block 1460, the merchant point of sale device 130 transmits transaction details to the account management system 160. For example, the merchant POS device 130 transmits transaction details comprising a transaction total, an account identifier of the merchant system, and the selection of the user 101 account payment option. In an example embodiment, the account management system 160 receives the transaction details over the network 170. In an example embodiment, the account management system 160 extracts payment account information from the user 101 account corresponding to the received selection of the user 101 payment account. In an example embodiment in which a discount or offer is applied to the transaction, the transaction total that the merchant POS device 130 transmits to the account management system 160 may comprise the total amount of transaction after the discount or offer is applied to the transaction.

In block 1470, the account management system 160 transmits a transaction authorization request to an issuer system 150. In an example embodiment, the account management system 160 generates a transaction authorization request comprising user 101 payment account information, merchant system payment account information, and a total amount of the transaction. In an example embodiment, the issuer system 150 receives the transaction authorization request from the account management system 160 via the network 170.

In block 1480, the issuer system 150 approves the transaction authorization request and transmits a transaction authorization approval to the account management system 160. In an example embodiment, the issuer system 150 subtracts the user's 101 current account balance from the user's 101 credit limit associated with the user's 101 credit account. In an example embodiment, if the difference between the credit limit and the credit balance is a positive number greater than the total amount of the transaction, the issuer system 150 approves the transaction authorization. For example, the user 101 will not exceed his credit limit if the transaction were to be approved, therefore the issuer system 150 approves the transaction authorization request. In an example embodiment, the account management system 160 receives the transaction authorization approval from the issuer system 150. In another example embodiment, the account management system 160 receives a denial of the transaction authorization request in response to the issuer system 150 declining the transaction authorization request. In an example embodiment, if the issuer system 150 approves the transaction authorization request, the issuer system 150 credits the merchant system account and adds a charge to the user 101 credit account statement, bank account statement, or other appropriate statement.

In block 1490, the account management system 160 transmits a transaction receipt to the merchant point of sale device 130. For example, the account management system 160 transmits a confirmation of the approval of the transaction or a notice of a declined transaction to the merchant POS device 130 over the network 170. In an example embodiment, the merchant POS device 130 prints a receipt comprising a summary of a successful or unsuccessful transaction via a printer device that is a component of or otherwise communicatively coupled to the merchant POS device 130. In another example embodiment, the account management system 160 may transmit a transaction receipt to the user computing device 110 to be displayed on the user computing device. In yet another example embodiment, the merchant POS device 130 transmits a transaction receipt to the user computing device 110 to be displayed on the user computing device.

ADDITIONAL EXAMPLE EMBODIMENTS

In certain example embodiments, a service provider system determines and/or verifies the identity of the user 101 for ends other than conducting a transaction via the application 113 and account management system 160. For example, reliable user 101 identification and/or verification from a candidate set of users 101 via facial identification may be useful for purposes of authentication, granting access, or personalizing experiences with the service provider system online and/or at a location associated with the service provider system.

In an example embodiment, gaining access to a service provider system location or authorization to purchase a product or service of the service provider system is restricted to a certain type of user 101 based on user 101 attributes or based on the identity of the user 101. An example user attribute is the age of the user 101. In this example embodiment, a user 101 signs into an application associated with the account management system 160 via the user computing device 110 and enters the service provider system location. The user computing device 110 receives a beacon device identifier from a beacon device installed at the service provider system and transmits the identifier to the account management system 160. The account management system 160 transmits facial templates corresponding to the user 101 and any other users 101 whose user computing devices 110 are in network range of the beacon device and who are signed in to the application 113 associated with the account management system 160 to a camera device installed at the service provider system location. The camera device captures a facial image of the user and identifies the user 101 by comparing the captured facial image against the received facial templates to find a match. In this example embodiment, the user 101 requests to access a restricted area, such as an area behind a gate, an office, or a room storing archives. In an example embodiment, the service provider system computing device transmits a request for the identity of the user 101 from the camera device directly or via the account management system 160. In this example embodiment, the service provider system computing device receives the identity of the user 101 along with user account information. In this example embodiment, based on the user 101 identity and/or user 101 account information and existing rules or regulations provided by the service provider system or existing legal rules and regulations, the service provider system computing device or service provider system computing device operator approves or denies an activity requested by the user 101 based on the user 101 identity and/or user 101 account information. For example, the user 101 is denied entry to a restricted area or denied access to restricted information.

For example, only users 101 who are employees of the service provider system are authorized to access a door to a restricted room at the service provider system location. In this example, the user 101 account information comprises a user's 101 name or identity. The camera device captures a facial image of the user and identifies the user 101 by comparing the captured facial image against the received facial templates to find a match. In this example embodiment, the user 101 requests to access the restricted area of the service provider system or otherwise unlock a restricted access door. In this example, the camera device transmits the identity of the user 101 to an appropriate device of the service provider system directly or via the account management system 160. For example, the computing device of the service provider system comprises an electronic lock or a device communicatively coupled to an electronic lock. In an example embodiment, the service provider system retrieves data comprising a set of user 101 identities allowed access to a restricted area. In an example embodiment, the service provider system computing device or service provider system computing device operator unlocks the electronic lock or otherwise allows access to the restricted area if the identity of the user 101 from the user 101 account information matches the user 101 identity of one of the users 101 in data comprising a log of users 101 allowed access to the restricted area. In another example embodiment, based on the identity of the user 101 not corresponding to an identify of one of the set of users 101 allowed access to the restricted area, the service provider system computing device or service provider system computing device operator does not allow the user 101 access to the restricted area.

In another example embodiment, a merchant system location or service provider system location provides a personalized one-on-one experience to a customer based on the customer's purchase history and habits. The process involves notifying clerks of the entry of a user 101 at the merchant location or service provider system location, the identity of the user 101, and any associated current or past purchase history that will allow the merchant system to streamline the experience and provide a satisfactory experience to the user 101 at the merchant system location. In an example embodiment, once the user 101 is identified via facial recognition, the merchant POS device 130 or other appropriate merchant system device or service provider system device displays details about the user 101 to the operator of the device. For example, the user's 101 name, nickname, interests, and/or other relevant data is displayed to the operator so that the operator can provide a personalized experience to the user 101. For example, the operator views the name of the user 101, “Charlotte Thomas,” displayed on the merchant POS device 130 and says, “How may I help you today, Ms. Thomas?” In this example, the merchant POS device 130 may display current or past purchase history of the user 101, for example, that the user 101 purchased a subscription to a merchant system service. For example, the merchant POS device 130 operator views the name of the user 101, “Charlotte Thomas,” and that the user 101 purchased a high speed internet service from the merchant system. In this example, the merchant POS device 130 may greet the user 101 as follows: “How may I help you today, Ms. Thomas?” and then follow up with “How are you liking your high speed internet service?”

In yet another example embodiment, a merchant system or service provider system may identify a user 101 to provide delivery to a user 101. In this example embodiment, the user 101 signs into the application 113 via the user computing device 110 and enters the merchant system location or service provider system location. The user computing device 110 receives a merchant beacon device identifier from the merchant beacon device 120 and transmits the identifier to the account management system 160. The account management system 160 transmits facial templates to the merchant camera device 140 corresponding to the user 101 and any other users 101 whose user computing devices 110 are in network range of the merchant beacon device 120 and who are signed in to the application 113. The merchant camera device 140 captures a facial image of the user and identifies the user 101 by comparing the captured facial image against the received facial templates to find a match. In this example embodiment, the user 101 requests to pickup and item that was previously ordered. In this example, based on the identity of the user 101 matching a user 101 identity associated with an item for pickup, the operator of the merchant POS device 130 or other merchant system employee delivers the item to the user 101. For example, the merchant POS device 130 operator determines the item for pickup associated with the identified user 101.
